Another Encounter With The Antelope Island Prairie Falcon

Two days ago we located the Prairie Falcon on the causeway once again. This bird spends most of its time on the island itself but occasionally ventures onto the causeway to hunt ducks. I’m quite sure, as are others who are more falcon knowledgeable than I, that it’s the same individual in all of my recent Prairie Falcon posts. Usually I complain about not being able to get close enough to my subjects but here I had the opposite problem. The only way I could even see this bird was from very close. From any further away the falcon was completely obstructed by the road edge and the vegetation growing there. The first two images are essentially full frame (very little crop) and that’s without my tc attached, so the falcon is too tight in the frame but this post is more about falcon adaptations than it is about aesthetics anyway. 1/1600, f/9, ISO 500, 500 f/4, natural light, not baited, set up or called in This bird was a mess! It had apparently just finished dining on duck so it was wet, blood encrusted and disheveled, with tidbits still clinging to feet and beak. The bird is meticulously cleaning and scratching its beak with those impressive talons, which seems to me to be about like picking one’s teeth with a Bowie knife. 1/1600, f/9, ISO 500, 500 f/4, natural light, not baited, set up or called in But what I found particularly interesting about many of the images I took of this bird was the good look at the well-defined and bulging crop. …

Northern Harriers Hunting

It’s getting to be what I call “harrier time” here in northern Utah so I thought I’d do a significant post on the species. For me, watching these birds hunt is absolutely mesmerizing and I could do it for hours. And I have – many, many times. But before I get into hunting I’d like to cover some basics on telling the sexes and ages apart. Sexual dimorphism in harriers is exceptional among birds of prey – telling adult males from adult females is easy because their colors are so dramatically different. But because juveniles of either sex strongly resemble adult females, that distinction becomes very tricky and causes a lot of confusion. So, here’s a primer: Adult males – gray above, mostly white below, black wing tips, lemon-yellow eyes Adult females – brown above, buffy with brown streaks below, lemon-yellow eyes (but in my experience, the eyes of adult females tend to be less bright than those of adult males) Juvenile of both sexes – similar to adult female but darker chocolate-brown above and strongly rufous (reddish) below Juvenile male – pale, greenish-yellow eyes Juvenile female – dark, chocolate-brown eyes All sexes and ages have the unique facial disc (ruff) characteristic of harriers. It’s not as prominent as it is in many owls but it can clearly be seen in this image. Its function is the same as it is in owls – to direct sound to the ears. Most hawks hunt almost exclusively by sight but because of their excellent hearing, thanks largely to the facial disc, harriers depend at least…

Prairie Falcon In Flight, With Prey

This image may look familiar to some viewers because I’ve previously posted another photo of this bird with a different wing position. I only got those two sharp shots of the falcon and I’d never processed this image before because the bird was too tight in the frame. I’d actually forgotten about this photo until recently when I decided it was worth making the effort to add some canvas to improve the composition. 1/2000, f/6.3, ISO 500, 500 f/4, natural light, not baited, set up or called in I found this juvenile feeding on its duck kill along the Antelope Island causeway last winter on a dark and blustery late morning. Two ravens began to harass the falcon with the apparent intention of stealing the duck so the rightful owner of the prey took off with the prize in tow. Within seconds, an adult Bald Eagle moved in and forced the falcon to drop the duck. One thing I find interesting about this image is the angle of the bird to the horizon – it looks like it’s flying downward, but in reality it’s actually gaining altitude. Normally, with the bird at this flight attitude, I’d rotate counterclockwise a little to make the flight angle more realistic looking, but since the horizon is in the background it’s obvious that the shot doesn’t need rotation since the horizon is level. The reason for the angled flight attack is the load that the falcon is hauling while it’s trying to gain altitude. The lower background is the dark, stormy and…

Delivering Food For A Family Of Short-eared Owls

I try not to play favorites when it comes to bird subjects for my photography but Short-eared Owls would have to be near the top of any such list I might make. I’ve had some luck with them here in Utah but my favorite area to photograph them is in southwest Montana. This series is from the summer of 2010 in Beaverhead County. I spent several days watching and photographing a male owl hunt voles and then bring them in for his family (female and two chicks) at the nest at the base of a sagebrush. I thought it might be interesting for some to see a full series of shots (of those I kept) as the male approached the nest with a vole. 1/1600, f/6.3, ISO 800, 500 f/4, 1.4 tc, shot from pickup window, natural light Like me, this male was a creature of habit. I would watch him hunting far off in the distance and when he was successful he would always repeat the same pattern. He would bring the vole in to the vicinity of the nest and then land on one of two favorite perches for a short time before delivering the vole to his family. This small sagebrush was one of those favorite perches – the other was a metal post. Here, he is in the process of landing and you can see the dark vole in his left foot. He always carried the vole to the perch in his left foot (as I’ve documented here) and always transferred…

Getting Close To The American Kestrel

One of the first lessons bird photographers learn (often to their great frustration) is that you must get close to your subject in order to get good detail. Very close. Even if you’re shooting with a long, expensive lens. And getting close usually ain’t easy! Large crops rob detail. I’m of the opinion that cropping away any more than about 50% of the image generally does unacceptable damage to image quality. Some species are relatively easy to approach – around here American Robins, Mourning Doves and House Finches come to mind. Other species have a reputation of being particularly skittish and at the top of that list for many photographers is the American Kestrel – a strikingly beautiful little falcon that is found throughout most of North America. For many years I’ve posted bird images on an internet avian critique forum and whenever I’d post a shot of a kestrel I’d invariably get comments that went something like this: “How in the world did you ever get this close to a kestrel? I always see them perched up high on poles or wires and whenever I even begin to get close they fly away”. Well, here’s the secret – photograph them when it’s cold. Very cold! That means in the depths of winter. It also means in the early mornings on those days when it’s coldest of all. I’ve found that many species of birds are more reluctant to fly in the cold but that tendency seems to be magnified with the kestrel. I’m not sure why but as a photographer I’m more than happy to…

Red-tailed Hawk Rejecting Intestines Of Prey

Many raptors will methodically and deliberately remove the intestinal tract of their prey before consuming it, a behavior that I’ve photographed several times with different species. In my research I’ve never been able to find out exactly why this is done – there are multiple theories but apparently no definitive answers. Maybe they tend to reject them because they “taste bad”, or because they “harbor harmful bacteria” or because they are filled with contents that are of “low food value”. Perhaps it’s a combination of factors. Recently, to add to the confusion, I’ve come up with my own working theory. The intestines of vertebrates, particularly mammals such as the rodents that many of these raptors regularly prey on, tend to be infested with a variety of parasites – including worms such as intestinal roundworms, flukes and tapeworms. The life cycles of many of these parasites are convoluted and complex but some of them lay thousands of eggs into the hosts intestinal contents every day. Eating those contents could have unpleasant consequences for predators so it seems logical to me that selection pressure might preserve such a behavior. 1/1000. f/5.6, ISO 640, 500 f/4, 1.4 tc, natural light, not set up, baited or called in While I was in SW Montana a few weeks ago this juvenile Red-tailed Hawk flew to a nearby post with a vole and started to eat it. It began by opening the vole and then removing and swallowing several desirable morsels. Here you see an errant feather floating away in the breeze. 1/1000. f/5.6, ISO 640, 500…

Escaped Falconry Bird – Peregrine Falcon

Early this morning, just as the sun was coming up over the Wasatch Mountains, we came across this adult Peregrine Falcon, with prey, along the causeway to Antelope Island State Park. It is apparently another escaped falconry bird as it had obvious falconry anklets above its feet, though the actual jesses had been removed. 1/500, f/5.6, ISO 640, 500 f/4, 1.4 tc This first image was taken where we first found it – along the edge of the causeway and next to the Great Salt Lake shoreline. A few seconds after this shot was taken the bird took off. 1/800, f/5.6, ISO 640, 500 f/4, 1.4 tc But seven minutes later, as we proceeded along the causeway, we found the bird perched on this highway post. 1/1000, f/5.6, ISO 640, 500 f/4, 1.4 tc This shot was taken as the falcon took off from the post. You’ll notice that the leather falconry anklets, sans jesses, are apparent in each of the above three images. 1/2000, f/5.6, ISO 640, 500 f/4, 1.4 tc And the last time we saw the bird it had landed far away on the large boulders lining the east side of the Antelope Island Marina. We’ve reported this sighting to the Utah Division of Natural Resources and they’ve told us that they will follow up on it. I’ve always admired the sport of falconry on several levels. Falconers generally have a deep devotion and personal attachment to their birds that I respect and they and their organizations have done a lot for raptor conservation…

Short-eared Owl In Flight, With Prey

I’ve been frustrated by this species in flight in Utah for years, though I’ve had some luck with Montana birds. 1/3200. f/6.3, ISO 500, 500 f/4, 1.4 tc Finally, last summer, I found a mated pair on Antelope Island who were busy trying to keep track of and feed at least four juveniles spread out over several acres. Occasionally one of the parents would fly by relatively close as it returned with a vole for the youngsters. In larger versions of this image there’s a catch light in the eye of the vole but it’s impossible to see at this size. Ron

Rough-legged Hawk Hunting Voles

Out of pure habit I still look for Rough-legged Hawks whenever I pass one of their favorite perches, despite the fact that they’re now on their arctic and subarctic breeding grounds in northern Alaska and Canada. Last winter it seemed that these hawks were everywhere in northern Utah and it wasn’t unusual for me to see a dozen or more different birds in a morning of shooting. They’re a particularly handsome raptor and I love photographing them. 1/3200, f/6.3, ISO 500, 500 f/4, 1.4 tc I found this one hunting voles along the Antelope Island causeway this past December. A moderate headwind slowed the bird down and made getting flight shots a little easier. 1/2500, f/6.3, ISO 500, 500 f/4, 1.4 tc When hunting they’re usually looking down which makes it difficult to get eye contact but occasionally you can catch them looking at you if you’re quick on the trigger. Here the wings are mostly horizontal but for me the tilt of the tail helps to compensate for that. 1/1600, f/6.3, ISO 500, 500 f/4, 1.4 tc This eye/head angle is more typical of a hunting bird. The position of the left wing probably won’t appeal to many but there’s something about the curves of both wings that I liked. The sky color may seem a little funky but that’s the color it really was so I didn’t play with it. 1/1600, f/6.3, ISO 500, 500 f/4, 1.4 tc Here the hawk has captured a baby vole. This surprised me a little…

Antelope Island – A Smorgasbord For Coyotes

A lot of folks don’t like coyotes but I’m in a different camp. I have great admiration for their adaptability, hunting skills, intelligence and communication abilities. Over the past few years I’ve had many opportunities to observe their behaviors on Antelope Island which has made me an even bigger fan of this amazing canid. To watch a coyote hunt is a fascinating experience. This post is meant as a documentation of the opportunistic feeding tendencies of the species rather than as a showcase for technically perfect photos. Getting clear shots of any mammal on the ground (as opposed to perched or flying birds) is a rarity because of all of the grasses, sunflowers, sagebrush, rabbitbrush and moth mullein the photographer has to shoot through on the island. So there’s lots of “stuff” in front of the coyote in some of these shots and a couple of them are sizeable crops but I think their prey tendencies are documented reasonably well by the images. 1/2000, f/7.1, ISO 500, 500 f/4, 1.4 tc Coyotes eat a lot of voles – prodigious numbers of them in fact. I’ve seen a single animal catch and consume 4-5 voles in the same area within just a few minutes and I’ve seen it several times. 1/1000, f/6.3, ISO 500, 500 f/4, 1.4 tc But they’ll also take birds when they can catch them. This coyote was returning from the lake shoreline with an unusual prize – some kind of waterfowl. From the position of the leg attachment at the back of the body I’d guess…

Short-eared Owls In Flight

These three images are of a mated pair of Short-eared Owls taken two years ago at Red Rock Lakes National Wildlife Refuge in southwest Montana. 1/1250, f/5.6, ISO 800, 500 f/4, 1.4 tc This is the male delivering a vole to his family. As you can see from my techs I had to max out my settings (especially on the last two images) to try to get enough shutter speed for flight shots. Each of these photos was taken on different mornings but the light was consistently a challenge while we were there. 1/800, f/5.6, ISO 800, 500 f/4, 1.4 tc This is the elusive female. I got very few shots of her because she spent most of the time on the nest with her two chicks and I rarely saw her fly. 1/800, f/5.6, ISO 800, 500 f/4, 1.4 tc Another look at the male. There’s a good reason for the timing of this post – we’re at Red Rock right now (I prepared this post before leaving and post-dated publication) and anticipation of this trip had me thinking about these wonderful owls again. We’d have to be pretty lucky to find cooperative owls again but if not there should be plenty of other birds to work with. The biggest challenge on this trip is likely to be light. Red Rocks is right on the continental divide and early summer weather up there is volatile and often down-right scary – especially when you’re pulling a camping trailer over 30 miles of dirt roads! These trips are…

Fledgling Loggerhead Shrike Learning The Ropes

Yesterday we came across this Loggerhead Shrike fledgling perched high and pretty in the early morning light. 1/500, f/8, ISO 640, 500 f/4, 1.4 tc A few minutes after this shot was taken the bird flew off so we decided to look for more opportunities elsewhere and left the area. 1/2000, f/6.3, ISO 500, 500 f/4, 1.4 tc Just before we quit shooting for the day we decided to look for the fledgling again in the same area as before. We found two of them this time – one flew off almost immediately but this one allowed us some close observations for about 25 minutes. By this time of the morning the bird was side-lit in most situations but we got to see some interesting behaviors. Typical of youngsters this one was curious about its surroundings and spent quite a bit of time exploring the greasewood bush it was in. Here it is about to half hop/half fly to the twigs in the upper left of the frame. 1/2500, f/6.3, ISO 500, 500 f/4, 1.4 tc Several times it picked off one of the drier greasewood buds and played with it for a while. 1/2500, f/6.3, ISO 500, 500 f/4, 1.4 tc But a parent coming in with food always got the full attention of the fledgling. In this image one of the adults is delivering a grasshopper to the begging young bird – you can just see the top of the parents head at the bottom of the frame as it works its way…

Pied-billed Grebe With A Mouthful

Just a single shot this time. I’m often blown away by the ability of some species to swallow huge prey whole when I have trouble gulping down anything much larger than an aspirin without chewing it first. 1/1600, f/6.3, ISO 500, 500 f/4, 1.4 tc A few months ago I watched and photographed this Pied-billed Grebe for 13 minutes as it tried to get this fish down its gullet. Other grebes attempting to steal the prize didn’t make the process an easy one but eventually the bird was successful. It’s not readily apparent in this shot but the fish was much wider than the head of the grebe. I could hardly believe what I saw… Ron

An Osprey, A Fish And A Thieving Magpie

Yesterday Mia and I returned from a three day camping and photo trip to Flaming Gorge. We had great weather for most of our time there and as usual the scenery and ambience were awesome. At an elevation over 6000′ many of the birds that we usually see there apparently haven’t arrived yet but we spent some quality time with a pair of nesting Osprey – a species that I’ve had little luck with in the past. 1/2000, f/5.6, ISO 500, 500 f/4, 1.4 tc This pole with all the attached ugly hardware was within a few feet of the nesting platform and early one morning this Osprey landed on the pole with a freshly caught fish. At first I figured that this bird would deliver the fish to its mate on the nest (I have a lot to learn about this species) but it didn’t. It’s intention was to eat the fish itself but as you’ll see, those plans were delayed by an interloper. It didn’t take long for this Black-billed Magpie to show up and torment the rightful owner of the fish. This Osprey removed and dropped the intestines in pieces and it seemed obvious to me that the magpie had learned that particular feeding pattern and came looking for tidbits that had landed on the wires below the Osprey. Here you can see one of those bits in the beak of the magpie that it had picked off of the metal above its head. So far the Osprey doesn’t seem too…

American Kestrel Eating A Vole (graphic)

A couple of months ago I came across this female American Kestrel along the causeway to Antelope Island. She had captured a vole and was in the process of eating it while perched on a road sign. The images I’ve presented here aren’t pretty and won’t appeal to everyone but as I’ve said many times before I’m fascinated by behaviors. 1//1600, f/6.3, ISO 500, 500 f/4, 1.4 tc She had already decapitated the vole and was in the process of disemboweling it when I found her. Kestrels routinely discard the intestines and she had previously removed the small intestine (portions of which can be seen near the underside of the tail). Here she is dropping the coiled mass of the large intestine. As she attempted to eat the vole the large intestine was right in front of her on the perch and she apparently found its presence right under her face as she dined to be offensive and distracting so she repeatedly tried to drop it over the edge of the sign to get rid of it. Three times she picked it up and dropped it but each time it landed on the edge of the wooden post without going over the edge. 1//1600, f/6.3, ISO 500, 500 f/4, 1.4 t Finally, on the third attempt, she succeeded in dropping it over the edge, but just barely. 1//2500, f/6.3, ISO 500, 500 f/4, 1.4 t Now with her dining table cleaned up she was able to attend to the rest of her meal. There…
